To all whom it may concern."

Be it known that LJAnns-PnAnson, a citizen of the United States of America, and a resident of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new 'and'useful 1m rovements in Spinning-Rings, of which the ollowing is a specification.

My invention relates to certain improvements in rings and ring-rails for spinning and twisting frames, and it consists, essentially, of a flangeless reversible vertical spinningring having a com aratively wide and shallow circumferentia central recess formed in its inner or concave face and one or more suitably located holes extending transversely through the wall of the ring and being in continuous open communication. with saidrecessed part;

It also consists in rovidingthe upper surface of the ring-raii: in which said ring isseated, with a narrow groove disposed concentrically with the ring, and short channels or ducts freely communicating with said lubrication of the said said ring-rail and rings.

groove and holes, all as more fully hereinafter set forth and claimed.

The obj ect' I have in view is to provide the rings and ring-rails of spinning and twisting frames with a simple, inexpensive and thoroughly efficient system for effecting the lubrication of the rings and travelers. By means of this invention or improvement the arts is or may be automatically accomplished while the machine is in operation; the working friction of the members is materially reduced, owing to the more perfect lubrication and the presence of the recessed part of the ring, therefore the machine may be run with less power; and the net product or out ut of yarnor thread is increased owing to t e lessened stopping of the machine and also to the fact that the yarn is cleaner since it is less liable to become soiled by the oil or lubricant used.

In the accompanying drawings, Figure 1 is a transverse sectional view, in enlarged scale, taken on line 11 of Fig. 2, clearly representing the invention in use as applied to a flangeless vertical and reversible ring and a reversible ring-rail, and Fig. 2 represents, in smaller scale, aplan view of a portion of the While various forms of spinning-rings may be provided with my improvement I prefer to employ a straight vertical ring without flanges, the wall of which is substantially uniform in thickness throughout. A ring of" this class as well as the ring-rail itself are readily reversible or capable of being i.n-'

verted, the rings being sim ly'forced in the" rail until they stand centra y of its web, that" is the center of the ring midway of its length is located midway of the webs thickness.

In the accompanying drawings a; designates my improvedspinning-ring as a whole, having suitable length 01' height, its outer and inner sides being substantiallystraight and concentric with each other. The inner or concave face of the wall is cut away to form a shallow recess of, the latter-being located' centrally of an extending say about one-third of the rings height or length, and having one or more holes a drilled transversely through the wall and being in continuous direct open communication with said recess.'

The traverse or ring-rail b-, represented in the drawings, isof the reversible type, that isthe two longitudinal front and rear edges thereof have each a rib or flange 6 arranged at right angles with the web part of the rail,

c intersected by short radial channels a lad- I ing to the said openings a of the ring.

Assuming now that a spinning or twisting frame be equipped with the improved ringrail b and rings a, and that wire travelers t are mountedand arranged on the latter substantially as usual, the operation is practically as follows: --The yarn or threadf as it passes downwardly to and under the traveler This latter, which I prefer to use in a slightly fluid state, is supplied from the annular resis wound upon the rapidly revolvin bobbin B (shown by dotted lines), thetrave er being ervoir or oove c' and its ducts c of the up per side the rail. The lubricant or grease softens sufficiently topass through the said open holes a registeri with the ducts and into the recess a of the ring. The traveler inf narrow and shallow annular recess formed in its concave surface for containing lubricant,

the wall of the ring being'further rovided with oil-holes extending transverse y therei through and being in direct communication withsaid recessed art.

7, 2.v ,The reversib e cylindrical-shaped spinning-ring herein described, the same compris ing a flangeless annular integral wall having rounded edges, a narrow and shallow circumferential recess formed in the concave side of said wall'and disposed centrally thereof for containing lubricant, and orifices extending transversely through the wall into the recess;

. rail an said adapted to be pressed into a ringretamed theremrpg friction, and

when in use having said 0 es of the ring arranged to register with the upper surface of the ring-rail.

3. A ring-rail having its web part provided with a hole adapted to receive aspinmnga oove formed in the u per surface of the ra s web for holding lu ricant, and short ducts leading from the groove to said hole, in combination with a flangeless spinning-ring removably seated in said hole of the ringrail, said ring having an inner circumferential shallow recess and transverse openings, the latter being in direct commumcation with said ducts and recess, substantially as described.

4. The combination of a flangeless spinning-ring rovided with an inner circumferentlal sh ow recess and transverse openings extending through the wall of the ring into the recess, a traveler member having a substantially straight shank supported on the ringland adapted to bear against the latter bot above and below the said recessed part,

and a rail having said ring removably seated therein, the upper surface of the rail being grooved and provided with branch ducts leading therefrom to said transverse o enings of the ring, substantially as herein efore described and-for thepurpose set forth.
